There is a bug in the project method of the LineSegment class

[wenshinlee]

LineSegment line1 = new(new Coordinate(0, 0), new Coordinate(0, double.MaxValue)); ;
Coordinate coordinate1 = new Coordinate(20, 10);
Coordinate coord = line1.Project(coordinate1);

coord is （NAN， NAN）

[wenshinlee]

In fact, the coordinates of coord should be (0,10).

[FObermaier]

NTS fails to compute a projection factor when the squared length of a line segment is greater than double.MaxValue.
This is an edge case, do you really need double.MaxValue as ordinate or is that just convenient?
